5 Best Free Virtual Machines in 2019 (+3 Free VM Backup Solutions)

January 7, 2019

Virtual machines (VM) come in all shapes and sizes.

A VM could come in the form of virtual desktop infrastructure or application runtime to a fully functional server or backup software system.

Virtualized applications, servers and other machines can be extremely helpful and provide scalable, versatile functionality for users. You can use virtual machines to try out a new operating system or create a virtual disk image of your hard drive. Or you could go even further and create an entire database server in the cloud.

Luckily, many virtualization technologies are free or open source. That will allow you and your company to save money when backing up your data or implementing process virtual machines such as applications or operating systems.

Virtual machines, for the most part, come in two forms: system virtual machines and process virtual machines. (We’ll stick to system VMs here since process VMs can come in too many forms to tackle in one article.)

What are Virtual Machines?

When we say system virtualization technology, we’re referring to fully virtualized machines capable of executing entire operating systems. These products capable of full virtualization live in our server virtualization software category.

The list we’ve outlined here includes any cloud computing server virtualization solution with an available free offering. It should be noted that this does not include products that are only free on a temporary basis, such as limited trial versions for new users.

These products alone have well over 100 validated user reviews on G2 Crowd as of December 18, 2018, and only represent a portion of the 50-plus server virtualization offerings listed on our platform.
